LUBBICLTING APPARATUS.

Specification of Letters Patent.

Patented Jan. 14, 1915).

Application filed November 8. 1915. Serial No. 60.297.

To all whom it may ooncmm:

Be it known that 1. James J. CARNEY, a citizen of the United States, andresident of Haverhill, in the State of lllassachusetts, have inventedcertain new and useful Improvements in Lubricating Apparatus, of

i which the following is a full. clear, and exact.

description.

This invention in lubricating apparatus swivels upon which the axles ofvehicles turn under the bodies thereof. and the object of the inventionis to provide a simple, durable, inexpensive and eliicient means forsupplying a lubricant to these swivels.

The swivels vary considerably in design but all consist of two more orless arcuate members bearing one against the other. The lubricatingdevice consists of one or more tubes of suitable length closed at theends to form a lubricant reservoir, secured in any suitable manner tothe upper member of the swivel, and provided with a suitable number ofoutlets communicating with the bearing surfaces.

in the drawings which illustrate the invention:-

Figure 1 is a plan view of a swivel showing one form of the device.

Fig. 2 is a pl'an view of another form of swivel showing a slightlydifferent. shape of lubricator.

Fig. 8 is a plan view of still another form of swivel showing a furthermodified form of lubricator.

Fig. 4 is a plan view of a further form of swivel showing a lubricator.as in Fig. 1, attached in a slightly different manner.

Fig.6 is an enlarged vertical section on the line 5-5. Fig. 1.

Fi 6 is an enlarged vertical section on the hue 6-6, Fig. 4.

Fig. 'i' is an enlarged section on the line 77. Fig. 3.

Fig. 8 is an enlarged section on the line S-8 of Fig. 1.

Before proceeding with the description. it must be understood that anyone of the forms of luhricator shown may be applied to any form ofswivel shown. or to any other form, if desired, so that the invention isnot limited to the particular combinations of specific forms.

Referring more particularly to the drawlugs, 11 designates the lowermember of the relates to improvements for turntables orswivel, which inFigs. 1 and 4 is a complete circle. in Fig. 2, two separated arcuatemembers, and in Fig. 3. a continuous arcnate member less than thecompletefcircle: and 12 designates" thoupper member of the swivel. whichin Fig. 1 is merely a bar having its ends hearing-on the lower member,but in the remaining figures is formed similarly t0 the lower member.The two members are revolubly connected by a boil or king pin 13. Itwill be understood that nothing of invention is claimed for thesemembers. as the forms illustrated are those commonly found in vehicles.one being attached to the underframe of the vehicle and the other to theaxle.-

The lubricating device consists of a tube 14 having closed ends 15,through one of which an aperture 16 is formed for the intrduction of thelubricant. These tubes 14 a-re'inounted on the upper swivel member 12and secured either by riveting or by clamps 17. Where the swivel memberis not of suitable form, a shallow channel 18 may be provided for thereception of the tube 14:, as clearly shown in Fig. 8. Before the tubeis applied. a suitable number of apertures 19 are drilled on an inclinethrough the upper swivel member, so as to open in the bearing surface.The tubes 14 are provided with apertures 20 which register with theapertures 19, so that the lubricant may flow from the tube through theapertures 20 and 19 to the bearing surface. The inclination of theseoutlet passages retards the flow of heavy lubricant used, so that acomparatively small supply of lubricant in the tubes will escape veryslowly and keep the swivel lubricated for a lon period of time. It isobvious that the lubricant will flow much more slowly through theinclined passage than it would through a vertical passage.

In Fig. 1, the tubes 14 are shown radially disposed, while in Fig. 2,the tubes, designated 14' are slightly curved in conformity with theswivel member and circumferentially disposed. Otherwise, the arrangement is exactly as described.

In Fi 5'. 3 and 7. a development of the idea. is ilustrated. Instead ofusing separate tubes on opposite sides of the center. a single tube 14"15 used, which extends diametrically across the swivel, being bentiniern'iediate the ends to pass the king pin. and provided with anaperture '21 communicating with the passage 22 formed in the swivelmember, through which lubricantv mayflow to the king pin.

Fig. 4 illustrates a slightly different method of attachment which maybe resorted. to where the-crossbar 12* of the swivel memher issufficiently thick and sufiiciently arched. Instead of clamping orriveting the tube in position, a pocket 23 is bored or otherwise formedin the swivel member into which the-tube l f'e'nters'. Thetube maybeheld in place" in this pocket merely by" the tightness of the fit, or byinterengaging strand I l't willbe obvious that a number of diflerentforms of tube and methodsof attachment aangbe devised, 'w'hichit'is' notpossible to screwtlireads 24 formed on the swivel mem-- contemplate inadvance, and that therefore,

all variations and modifications which in l'udei a reservoir supp-lyinlubricant thrown: an inclined passage must be cont atassaacladeai thepresent invention. It will alsdbe" understood that if it; isdesired toregulate or entirely shut o'fiftll'efi'ow of lubricant, this may be doneby turning 'Ito bring its apertures out of register with the passages inthe swivel member.

Having thus described my invention, What I- claimist- 1. In a device ofthe character described, the combination with upper and lower swivelmembers having a lubricant passage in the upper member, and a lubricantreservoir rotastably mounted on said member having an outlet movableinto and out of register with the passage by rotation of the reservoir;

2. In a device of the character described, the combination with upperand lowerswivel members revolub'ly mounted on a bolt; the upper memberhaving passages through which a lubricant isadapted to pass'to the lowermember, a reservoir extending across the" upper member and havingpassages alinin'g' with the passages in the upper-memher and means forlubricating the bolt trom the reservoir, substantially as described.

In witness whereof, I have hereunto set my hand, in presence of two"witnesses.

. I JAMES J. CARNEY.'
